ttf-Claims. 1.

This invention relates to improvementsin gates for enclosures,v such asfarm gates, andmorepanticularly to extensible `gates which maybeadjusted in length.

One of the objects of the invention is to provide a gate withteleseopiceXtensible-sections, the eXtensible sections all telescoping intovthefirst, or hinged-section, to minimize the gate size to facilitateshipping thereof.

Another vobject is to providea gate of the fore; going type -in whichthe-length of the gate may be readily adjusted to t between vgate ,postsof an enclosure.

Another object isto providea gate which is extremely strong inproportion to its weight.

Another object is to provide a gate of i welded tube construction'whichhas a Vminimum number of parts.

A further Objectis toprovide a gate `whiclrmay be economicallymanufactured Still further objects, advantages,` and salient featureswill become'more apparent froma consideration of the description tofollow, `the appended claims, and the accompanying drawing, in which: I

Figure 3 is an enlarged section taken on line 8 8, Figure. 2; `andFigure 9 is an enlarged section taken on line 9 9, Figure 2.

Referring Vin detail to the drawing, and, particularly Figure 1, thegate comprises in general, a plurality' of sections I0, Iv I, and I2,sectionv I0 being pivotally supported on a post I3, the lower end ofwhichA is embedded in concrete.

Section I comprises a vertical metal tube I4 which telescopes over postI3, as best shown in Figures and 6, post I3 being provided with a collarI5, welded to the post, which provides a thrust bearing for tube I4. Theupper end of post I3is threaded and receives a pipe cap I6 which closesthe-upper end ofthe post andfalso serves as lan abutment for the Aupperend of tube I4. Fittings It-'I arerprovidedon the tube, these being ofany well knownftype, for Vreceiving the end of a-grease gun `sothatfgrease may be forced between -post I3 fand tube I4. A plurality-'ofhorizontal tubes 18', i9, 20, and 2I are contoured at their left ends(Figure 1) tot tube I4, as' shown at 22-1in Figure f7,andareweldedthereto, with a weld which extends around the curved ends ofthe horizontal tubes, lwhere they join with tube I. Spacer tubesf23;24,' and25 are similarly contoured at their-upper and lower ends andare-welded, respectively, to tubes I8 and I-S I9 andIEll, and 20`and-ZI. Gusset plates 2ia're welded to the various- `horizontaltubesand the vertical tube, in the'arrangement shown in Figure 1.Alternatively, diagonal braces extending between opposite cornersof `therectangles-formed by the horizontal and vertical tubes may be employed.Section. I I comprises horizontal tubes 21;'28, Z9 and 3i) which are of"such size that they tele'- scope, respectively` within tubes I8, I9,`2U and ZI vof section I0; Spacertubesl, 32qand '33 arel contoured attheir `upper and vlower ends and welded tothe 'fhorizontaltubes inthesame mau'- ner as the vertical spacer tubes of section I0. Section I2Vcomprises horizontal tubes '34, v35, 3S and `3l which are of `such sizethat they telescope, respectively, within tubes 21, "28, A29'and 30; Theright ends of these tubes are contoured'and welded to a single verticaltube 38 in the saine manner explained in connection with tubes t3 to Z'Iwheretheyjointubel. f A plurality of apertures `39 are provided in eachofthe horizontal ltubes through which bolts' 4B" passA toV thus securethe sections together in a desired position. AIn event' the openingbetween fence posts is such that :the gatedoes not iitga's desired, withthe apertures '39; as provided, cross holes such as v39 are merelydrilled through the horizontal tubes for the reception of bolts 49'.'

The gate may be varied in size, as desired, and the` number of sectionsincreased or decreased.. A gate A'which vhas been found very versatileis about five feet high and' each section aboutsix feet long,tl1etubingin the lsection IIlJbeing aboutv one and one' half inches in diameterandabout fourteen gage in thickness. The tubing in section I I is, ofcourse, slightly smaller in diameter, and the tubing in section I2slightly smaller in diameter than that of section II. This provides agate which may be extended to about fifteen and one half feet. Ifgreater length is desired more sections may be added, or alternatively,two gates may be provided, one hinged adjacent each fence post 4l, 42.Thus, an opening of about thirty one feet between fence posts may beaccommodated with two gates of the dimensions above given.

As shown in Figure 2, the gate may be telescoped to the length ofsection' I0 plus the diameter of the vertical spacer bars Eon section Il and spacer bar 38 on section I2, that is, the dimensions of the entiregate when contracted is only slightly longer than section I0. Thisfacilitates shipping of the gate and also reduces shipping and storagecosts since the bulkiness of goods is a factor of such costs. A1so,aminimum numi.

ber of parts are employed in the gate lwhich reduces its weight and costof manufacture.

While the various joints have been described as weldedf this term is tobe construed in the claims in a generic sense and to include joining 0fthe metal tubes by a dissimilar metal, for example, brazing when steeltubes are employed. Other modifications will occur to those skilled inthe art and hence the specific structure illustrated is to be regardedas exemplary only and the scope of the invention is to be measured bythe appended claims construed in the light of the spirit of the entiredisclosure.
